• Before installing the front panel, make sure the indoor unit is square with the ceil-
ing opening (or parallel to the angle between the wall and the ceiling).
• Check that the four points where the front panel will be secured are in contact
with the ceiling surface.
• Check that the insulation for the refrigerant pipes, drainage pipes, etc. is in place

• Adjust the front panel so that it fi ts properly in the angle between the ceiling and
the wall, and install the securing bolts 2 (supplied with this grille) in their four
places at left and right, leaving them slightly loose. (Fig. 5-5)
• Next tighten the securing bolts 2 and securing screws 3 in the centre three
places.
• Finally tighten the securing bolts 2 in the four places at left and right.
• At this point, make sure there are no gaps between the indoor unit and the front
panel, and between the front panel and the ceiling surface. If there are gaps, the
wind may come in and it may cause water to drip (Fig. 5-6).
* Tighten the securing bolts 2 and securing screws 3 completely.
• Replace the air fi lter and screw cover, and press the intake grille on the place
marked Push until you hear it snap into place.
